This montage is slightly different and perhaps a bit longer than the one seen at the end of the 1992 Chaplin film. It was compiled by Peter Bogdanovich & Richard Patterson, who directed the 1975 documentary, The Gentleman Tramp. The man speaking at the very beginning is Academy president Daniel Taradash.
Charlie must have loved hearing the audience's laughter during these clips.
